WHEEL- SPECIFICATION forming part of Letters COLTER.

Patent No. 256,941, dated April 25, 188:,

Application filed December 2, 1851. (N model.)

To all whom it may concern:

Be it known that I, WILLIAM B. YOUNG, of Alton, in the county of Madison and State of Illinois, have invented a new and useful Improvement in Wheel-Colters, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to journaling wheelcolters.

Figure 1 is a central horizontal sectional View through the colter embodying my invention, showing how the cap-bush A and plugbush B are arranged. Fig. 2 is a perspective view of the outer end of the boss 0. Fig. 3 is a perspective view of the cap-bush A. Fig. 4

is a perspective view of the plug-bush B.

Referringtothe drawings,D is a cireularcoh ter-blade, having a central hub or boss, as in ordinary common eolters. The outer end of the boss O,- I construct with a cylindrical part,

a, with the shoulder y and pin-clutch b, as shown in Fig. 2.

Ais my improved removable capbush, having the recess d, with the slit 0 and shoulder r, with a bearing part, c. The capbush A is seated around and over the end of the boss O by the part a, fitting into the recess 07, and the clutch b,fittinginto the slitc, as showninFig.1.

B is the plug-bush, having a cylindrical 0 part, 7.", on which the bearing 0 is seated, also having the oblique shoulders m, bearing on the outer end of tbecap-bush, also having a square part, 71-, to which the yoke may be connected.

In operation the cap-bush Acovers the end of the boss 0 and is heldin position by the clutch 5 b, and is thereby caused to revolve with the colter. The plug-bush B furnishes a straight cylindrical'bearing and also the oblique shoulden-bearing, as shown. The central bolt is closely fitting the perforation p inv the plug- 40 bush, holding the plug-bush in line without wear to the bolt, and by tighteningthe nut on the bolt the parts are held snugly together the colter pivoting on the shoulders or and hearingc,andanylooseningot'theboltcannotcause 5 the colter to wabble, while the bearinge is on the straight part 7c. The plug-bushB is held from rotating by the square part h when seated in the colter-yoke.

I. preferably make both bushings of hard \vhitemetal, and both bushings, being removable, may, when worn, be changed for new at slight expense.

Havingthusset forthmyinvention,Iclaim In a wheel-colter, a hub-boss having the bearing a, shoulder y, and clutch b, in combination with the cap-bush A, having the re cess d, with slit a, shoulder r, and bearing e, and with the plug-bush B, having the bearing k, oblique shoulder or, and extension 72, all arranged and operating substantially as and for the purpose-set forth.
